今年春节档上映的硬核科幻电影《流浪地球》成为今年第一部爆款国产影片。据统计,《流浪地球》上映34天时的票房已累计达46亿,一举把2019年奠定成为“中国科幻元年”。谈科幻电影必然绕不开特效,电影中呈现出的逼真特效技术引发了观众的热议,而这些令人震撼的特效基本都是出自国内团队之手。但影迷第一时间想到的往往是电脑特效,在此前的舆论场中,关于《流浪地球》中特效的评价,也多以电脑特效为主,也就是CG,很少有人提到片中的物理特效(也叫“实体特效”)的部分,而实际上,那些被统称为“道具”的“物理特效”正是后期电脑特效的基础,物理特效道具越真实,后期效果才更能给观众代入感。本期特别策划中,我们专访到几乎承包了《流浪地球》物理特效制作的mdi工作室的主创成员。《流浪地球》片中出现的宇航服、外骨骼服装、枪械、点火石、休眠舱、气囊球等都出自mdi设计师和工程师之手。这群一直埋头苦干的青年设计师们不仅实战技术过硬,更令人惊喜的是,接触过国外电影及特效制作环境的他们,不仅拥有比前辈们更广阔的的视野、更高层次的认知,对中国电影工业化也有着自己的思考。面对未来,他们有着乐观而审慎的规划,预备脚踏实地地通过工业设计将中国电影工业化的进程不断推进。
